Australia, the flattest, driest, and geologically oldest vegetated continent, has a uniquely high proportion of nutrient‐poor soils. We develop a “Nutrient‐Poverty/Intense‐Fire Theory,” which postulates that most anomalous features of organisms and ecosystems of Australia are the evolutionary consequences of adaptations to nutrient poverty, compounded by intense fire that tends to occur as a result of nutrient poverty. The fundamental tenet of the theory is that plants growing in environments… Expand
Constraint on woody cover in relation to nutrient content of soils in western southern Africa
The influence of soil nutrients on woody plants is poorly understood. Are trees – fire and other disturbance factors being equal – generally promoted by nutrient-rich or by nutrient-poor soils? ToExpand
Mineral Nutrition of Plants in Australia’s Arid Zone
Australia’s arid-zone soils are highly leached and resorted (Winkworth 1967; Pillans 2018) and characterised by low levels of available water and nutrients (Orians and Milewski 2007). These soils areExpand
Do nutrient-poor soils inhibit development of forests? A nutrient stock analysis

Nutrient-poor soils often support low-stature grasslands, savannas and shrublands where the climate is warm enough and wet enough for closed forests. Though this pattern has long been recognised, theExpand
Combustion temperatures and nutrient transfers when grasstrees burn
Abstract Fire controls the structure and functioning of many ecosystems, especially through its effects on biomass and nutrient cycling. Fire mineralizes soil nutrients and returns plant-lockedExpand
A fresh framework for the ecology of arid Australia
Fourteen propositions distil the argument that most features of the Australian deserts are explicable in terms of two dominant physical and climatic elements: rainfall variability, leading to extended droughts and occasional flooding rains; and widespread nutrient poverty. Expand
The phosphorus-rich signature of fire in the soil-plant system: a global meta-analysis.
A global-scale meta-analysis of soil studies and litter studies found that fire led to significantly higher concentrations of soil mineral P as well as significantly lower soil and litter carbon:P and nitrogen:P ratios, and suggested that burning can ease P limitation and decouple the biogeochemical cycling of P, carbon and nitrogen. Expand
The stoichiometric legacy of fire regime regulates the roles of micro-organisms and invertebrates in decomposition.
The results reveal that high-frequency fire regimes promote nutrient-poor, carbon-rich ecosystem stoichiometry and, in doing so, disrupt ecosystem processes and modify the relative functionality of micro-organisms and invertebrates. Expand
Stoichiometric patterns in the responses of organisms and ecosystems to fire
Vegetation fire is an important driver of ecological and biological structure and function on the Australian continent. An enhanced understanding of fire’s role in this context will be essential asExpand
The roles of climate and soil nutrients in shaping the life histories of grasses native to the Cape Floristic Region
AimsWe hypothesized that in seasonally-arid systems the evolution of annuality is controlled by both moisture regime and substrate quality, with infertile soils either precluding annuality orExpand
Plant mineral nutrition in ancient landscapes: high plant species diversity on infertile soils is linked to functional diversity for nutritional strategies
Ancient landscapes, which have not been glaciated in recent times or disturbed by other major catastrophic events such as volcanic eruptions, are dominated by nutrient-impoverished soils. If theseExpand


The role of resource imbalances in the evolutionary ecology of tropical arboreal ants
Dietary ratios of CHO:protein play an important and previously unrecognized role in the ecology and evolution of ants generally and modifications of worker digestive systems in certain ant sub-families and genera represent key innovations for handling and processing large volumes of liquid food.

Nutrient distribution in karri (Eucalyptus diversicolor F. muell.) ecosystems in southwest western Australia
Abstract Estimates have been made of the quantity of nutrients in above-ground biomass, including overstorey trees and understorey shrubs, in litter on the forest floor, and in soils to a depth of 90Expand
A framework for the ecology of arid Australia
There have been few attempts to describe the key ecological relationships which may be controlling the biotic structure of the Australian arid zone. We develop a series of ‘propositions’ which stateExpand
Convergence and non‐convergence of plant traits in climatically and edaphically matched sites in Mediterranean Australia and South Africa
This paper compares the occurrence of plant traits in five edaphically matched sites at the Barrens, southwestern Australia and the Agulhas Plain, southwestern South Africa. The two regions are veryExpand
The Occurrence of Seeds and Fruits Taken by Ants Versus Birds in Mediterranean Australia and Southern Africa, in Relation to the Availability of Soil Potassium
It is proposed that unusual interactions between plants and animals have arisen in Australia because of a unique physical environment rather than the isolation or genetic limitations of the flora and fauna. Expand
The composition of several arid spinifex grasslands of central Australia in relation to rainfall, soil water relations, and nutrients
The uniformity of vegetation and soils was the outstanding feature in communities of Triodia basedowii and Plectrachne schinzii, which occur on extensive tracts of featureless sand plains and are a stable edaphic climax subject to and adapted to repeated burning. Expand
Utilization of termitarium soils by éléphants and its ecological implications
ummary African elephants in moist dystrophic savanna woodlands were observed to excavate termite mounds and to eat soil. Soil from termite mound eating sites showed an elevated pH level and clayExpand
A Comparison of Ecosystems in Mediterranean Australia and Southern Africa: Nutrient-Poor Sites at the Barrens and the Caledon Coast
This article's comparison of two carefully chosen areas, the Barrens in med Mediterranean Australia and the Caledon coast in mediterranean southern Africa, is timely. Expand
Nutrient distribution in a jarrah (Eucalyptus marginata Donn ex Sm.) ecosystem in south-west Western Australia
An estimate has been made of the quantities of nutrients in trees, shrubs, litter and soil at a jarrah forest site near Dwellingup, Western Australia. This shows that the nutrient status is lowerExpand
This study of the fate of honeydew and associated metabolites within a forest stand shows that the concentrations of DOC and hexose-C in throughfall were reduced on the way to the soil and that there were no differences in the soil solutions from infested and uninfested stands, however, the distribution and abundance of Honeydew-producing Homoptera had a marked effect on the spatial and temporal variability in the DOC concentrations in through fall.
